#1 of 16 gas tank pressure by redshamrock Feb 26, 2008 (8:18 am)
I have an 04 colorado crew cab overall i love it. its got about 86000 miles on it. WHEN I bought it (brand new) i had some serious electrical problems and had the bcm replaced 4 times finally fixed!REcently i went to pump some gas and the pumped clicked off at $3...i was on empty so i knew it wasnt full yet!!! So now everytime i go i can hear pressure build up then the pump shuts off and when the pressure is released i can resume pumping. I called the dealership and i got the "well youll have to bring it in so we can teake a look, not a clue what it could be"!! dont really have the $60 bucks for them to check it out, i do all the maintenance myself, spark plugs fuel filter ect, so if anyone has any clue what it could be please let me know Replies to this message: poncho167 (Mar 01, 2008 5:26 am) redshamrock (Apr 16, 2008 8:47 am) poncho167 (Apr 19, 2008 5:13 am) and 1 more...

Replying to: redshamrock (Feb 26, 2008 8:18 am) Sorry I can't help you with the issue, but most small shops will give you a free estimate of what needs to be fixed. Are you using the same gas pump at the same station? Replies to this message: redshamrock (Apr 16, 2008 8:47 am) poncho167 (Apr 19, 2008 5:13 am) poncho167 (May 10, 2008 6:30 am)

Replying to: poncho167 (Mar 01, 2008 5:26 am) i have talked to a few people and they said it could be my "vent control valve" is stuck shut. Any feedback on this would be appreciated and if so any clue where that is located?thanks Replies to this message: poncho167 (Apr 19, 2008 5:13 am) poncho167 (May 10, 2008 6:30 am)

Replying to: redshamrock (Apr 16, 2008 8:47 am) I don't have a Cobalt, but the vent control valve that I think they are referring to should be connected to your air filter system. I could be wrong but there is a valve door on my trucks air cleaner ducting that opens and closes. Mine currently is always in the open position because it doesn't really matter in my truck. There is also an exhaust gas container that contains charcoal for excess fuel vapor flow but this shouldn't be related. I can't say anymore. The only other valves that are related to gas but maybe not in your situation is the EGR (exhaust gas recirculator) valve on my S10's intake manifold.
